So two layers of CDX 3/4 ply bolted together. One 3/8 ply screwed to the top. No glue used with the idea I may want to disassemble it later. I also do not have any screws in the middle of the field. Now I’m thinking glue and countersink a couple screws in the middle.

I built my entire bench out of plywood, 3 sheets of 3/4” AB sand ply, legs, stretchers and all.

I screwed and glued the top together. Four layers thick, topped with MDF and hardboard which are replaceable.i put screws on 8” centers.

After using it for 3 years I wish I had removed the screws from each layer after the glue dried before adding the next layer.

Would have taken a little longer to build, because I did the entire top in one day, but then I wouldn’t have to worry about hitting a screw when drilling dog holes. Don’t ask how I know that is a problem.

One other very important consideration, which I did take care of, is to be absolutely sure the top is level and not twisted or bowed. If you glue it up with a twist in it, there is no way to un-twist it after the glue sets.

I see. This is great input. Now let me share an idea. I’m going to use the bench for face frames and pocket screw projects. I was contemplating throwing some linoluem tiles on the surface. Makes for a smooth finish and helps hold the wood in place. Thoughts?

Advice taken: a couple more screws countersunk into the center field. Now the surface is rock solid and glass smooth.

Next is the addition of a power strip mounted on the bottom of the surface. That way I won’t accidentally run into a plug or three. Then thinking of additional storage. A nice couple hooks for a level and clamps.
